PLOS partners with Cold Spring Harbor Laboratory to make posting preprints in the life and health sciences seamless and convenient.
Authors posting preprints to the bioRxiv or medRxiv preprint servers can choose to concurrently submit their manuscripts to PLOS Medicine or another relevant PLOS journal through the direct transfer service. Learn more about posting a preprint and the direct transfer service offered by bioRxiv and medRxiv.
Authors invited to make a full submission to PLOS Medicine may opt-in to have PLOS forward their submission to medRxiv for consideration for posting as a preprint.
Papers that pass an initial screening for suitability will be posted on medRxiv as a preprint, meaning that the manuscript files will be made publicly available and credited to the listed authors. If the article is later accepted for publication in PLOS Medicine, the preprint and published article will link to each other when the article appears online.
Preprints appear on medRxiv in PDF format. Authors can choose to supply their own preprint PDF or have PLOS Medicine compile an automatically generated PDF.
- If you supply a preprint PDF it will appear on medRxiv unchanged. Be sure to include title, authors, abstract, and the full text of the manuscript, along with any figures or tables and their captions. medRxiv limits PDF file size to 40 MB or less. PDF files must be compressed to meet this requirement.
- Alternatively, PLOS Medicine can automatically compile a preprint PDF suitable for medRxiv from the manuscript file and figure files that are part of your journal submission. Supplementary information will not be included in auto-generated preprints, but may be uploaded directly to medRxiv after posting.
After authors have opted in to have their preprint posted by PLOS Medicine, it is transferred to medRxiv where researchers with relevant expertise screen preprint submissions for suitability. More information on the screening process can be found here.
Most submissions that pass medRxiv’s preprint checks will be posted within a few days of submission. Authors will receive a notification of successful preprint posting directly from medRxiv. Once posted, a preprint cannot be removed from medRxiv.
medRxiv will communicate with authors directly if issues arise or screening indicates that a manuscript is not eligible for posting.
To ensure that readers are always accessing the latest version of the manuscript, authors are encouraged to submit updates and revisions to medRxiv directly up until the point of acceptance for publication. Consult the submission guide at medRxiv for specific instructions.
If a concern arises about a published PLOS article with a related preprint, PLOS will evaluate the concern according to our standard editorial processes, taking into account any relevant comments available on the preprint.
